rtw88: add h2c command in debugfs
It's very useful to send H2C command for debug usage. Add an entry for sending H2C command to firmware. usage example: echo 42,00,00,43,02,00,00,00 > /sys/kernel/debug/ieee80211/phyX/rtw88 Signed-off-by: Tzu-En Huang <tehuang@realtek.com> Signed-off-by: Yan-Hsuan Chuang <yhchuang@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20200717064937.27966-8-yhchuang@realtek.com
